Files.readAllLines method returns a List of String, with the content of the text file, Files has also the method readAllBytes, returns an array of Strings. Files.write method writes byte array or into an output file, indicated by a Path object. Files.write method also takes care of buffering and closing the output stream. Notes on the C# ...
Value types (such as int, double, etc.) are created in a sequential structure called the "stack". VB .NET and C# also allow the use of the new operator to create value type objects, but these value type objects are created on the stack regardless of whether the operator is used or not.
The OptimJ programming language is an extension of Java 5. As does Java, Optimj provides maps; but OptimJ also provides true associative arrays. Java arrays are indexed with non-negative integers; associative arrays are indexed with any type of key.
Here a whole switch expression can be used to return a value. There is also a new form of case label, case L-> where the right-hand-side is a single expression. This also prevents fall through and requires that cases are exhaustive. In Java SE 13 the yield statement is introduced, and in Java SE 14 switch expressions become a standard language ...

The goto statement can be used in switch statements to jump from one case to another or to ... in C++ and Java. An array in C# is what ... a new value, but the ...
In this case an implementation can be represented as a lambda expression instead of implementing it in a new class, thus greatly simplifying writing code in the functional style. Functional interfaces can optionally be annotated with the @FunctionalInterface annotation, which will tell the compiler to check whether the interface actually ...
As an example, consider a need of extending the string class with a new reverse method whose return value is a string with the characters in reversed order. Because the string class is a sealed type, the method would typically be added to a new utility class in a manner similar to the following:
